DESCRIPTION OF THE PREFERRED EMBODIMENTS

As explained above, the invention relates to a communication device between an audiovisual information playback system, hereafter called a jukebox, with the aim of simplification, and at least one electronic game machine.

The invention will now be described with reference to FIG. 1. An example of a jukebox 1 is described in the European patents EP 786 212 and EP 786 122 filed by the applicant. Such a jukebox 1 substantially comprises a means of payment, a viewing means associated with a means for interacting with the user, a sound playback means and a mass storage means for storing a plurality of musical selections. The jukebox 1 may also comprise a modem 13 or equivalent means for communicating with a remote server 5, e.g., for updating the library of musical selections.

In order to specify the context of the invention, it should be understood that the electronic game machines 2 are for instance electronic games or internet access stations. Thus, the electronic game machines 2 do not originally provide functionalities such as that of a jukebox or a jukebox terminal.

As a minimum, each electronic game machine 2 must originally comprise a viewing means 210, such as a video monitor, a means for interacting with a user 211, and its own means of payment 220. The interactive means 211 include for instance either a touch screen or a mouse-like pointer, or else push buttons or a keyboard.

The principle of the invention is that these electronic game machines 2 can be used as add-on selection means and means of payment for a jukebox 1, located nearby, in the same bar as the electronic game machines 2. Thus, each electronic game machine comprises a means for selecting between two operating modes. The first operating mode corresponds to the original operating mode of the electronic game machine, i.e. the machine is operating as an electronic game or an internet access station. In this mode and according to a first alternative embodiment, no communication is taking place between the jukebox 1 and the electronic game machine 2. In the second operating mode, the electronic game machine 2 is converted into an add-on selection means and a means of payment for the jukebox. In this mode, all the original functionalities are unused to allow for the selection and payment functions of the jukebox 2.

According to the invention, each electronic game machine 1 is fitted with a means 23 of connecting to a local communication network 3. The main feature of the local communication network 3 is that it must be bi-directional. Thus, the LAN 3 can be for instance of a radio frequency or of a wired type, or else it can use electric carrier currents. Preferably, in order to restrict installation costs, the connection means 23 will be chosen to be adaptable to an existing LAN. Also, the jukebox 1 furthermore comprises a means 11 of the same type for connecting to the local communication network 3.

Thus, via an appropriate communication protocol, the jukebox 1 can send and receive messages to and from each electronic game machine 2 through the local communication network 3. Management of the dialog with each electronic game machine 2 is provided by a special so-called dialog module 10 of the jukebox operating system.

The type of connection between the game machine 2 and the jukebox depends on the quantity of information to be transmitted to the game machine 2. The greater the quantity of information, the higher the throughput of the connection must be so as not to hinder the operation of the game machine 2.

Similarly, as a general rule, the type of connection between jukebox 1 and server 5 is different from the type of connection between game machine 2 and jukebox 1. Indeed, the communication between the jukebox and the server is rather of the long-range type when the connection between the game machines 2 and the jukebox 1 is rather of the LAN-type.

According to the invention, the interactive means 211 of each electronic game machine 2 comprises an activation means allowing switching of the operation of the electronic game machine 2 from a normal mode to the jukebox terminal mode, or vice versa. This activation means can consist, for instance, of a virtual button displayed on the monitor of the game machine 2 and onto which a pointing device (mouse cursor, or user's finger, or light pen) is moved for activating the functionality associated with the button. Also, each electronic game machine 2 comprises a means 20, 21, 22 of managing a viewing means 210, an interactive means 211 and a means of payment 220 to provide the operation of the electronic game machine 2 according to the second mode. Indeed, the second operating mode requires the viewing of specific selection screens as well as different management of the means of payment in comparison with the first operating mode of the electronic game machine 2.

These specific means are for instance software modules 20, 21, 22, e.g. loaded when the modification of the machine is installed and which belong to or are added to the operating system of each electronic game machine 2. The specific means also comprise an interface 23 communicating with the connection means comprising notification means so that each software module can transmit notifications or receive messages from the jukebox 1.

A first so-called supervisor module 20 comprises e.g., a first routine, respectively a second routine, that manages initialisation, respectively termination, of the operation of the electronic game machine 2 in the second operating mode, i.e. in the mode allowing the selection and payment for pieces of music from the jukebox 1.

Thus, when the game machine 2 is operating according to the first mode, a user selecting the activation means initiates the first routine of the supervisor module 20 which is then activated for initialising a second module 21, called the graphic management module. The graphic management module 21 is for managing the selection means 211 and the viewing means 210 of the electronic game machine 2. The supervisor module 20, via the first routine, initialises a third module 22 for managing the viewing of the means of payment 220 of the electronic game machine 2 according to the second mode.

The supervisor module 20 comprises a means for also initiating the sending of a message, via the notification means, through the LAN 3, to the jukebox 1, in order to notify the dialog module 10 of the jukebox 1 that the electronic game machine 2 has switched to the second mode. Upon receipt of this notification, the jukebox, via the dialog module 10, becomes the master of the dialog with the electronic game machine 2 and all the game functions of this machine are ignored. In response to this notification, the dialog module 10 comprises a means of sending messages to the graphic management module 21 which allows graphic user dialog screens to be displayed. These screens are for guiding the user when choosing songs and using the game machine 2 as the add-on selection means and means of payment of the jukebox.

Also, the interactions of the user with the selection means 211 of the game machine 2 are translated by the graphic management module 21 into messages that are then transmitted via the notification means to the dialog module 10 of the jukebox 1 to initiate the corresponding action, i.e., send the information allowing a screen display, to the machine 2 or validate a user choice.

According to the invention, the welcome screen sent and then displayed by the graphic management module 21 on the viewing means 210 of the electronic game machine 2 prompts the user to select a song from among the collection of songs available on the juke box. This welcome screen also includes a first display area containing the amount of money available to buy one or more credits. A credit represents the possibility of validating a musical selection to prompt its playback. Hence the amount available corresponds to a sum of money which has not been used by the user to pay for credits so as to purchase plays of songs or to pay for credits in order to be able to play a game on the game machine. A second display area contains the number of remaining credits to be used for the operating mode as a juke box terminal. The amount available is, for example, stored and administered by the management module 22 of the payment means of the game machine 2.

In an embodiment variant where the game machine 2 permits the user to accumulate points usable in the game machine 2 in order to obtain new game credits, the module 22 for managing the payment means may include a sub-module that uses a rule for converting accumulated-points into an available sum of money. Consequently, when the welcome screen is displayed calculation means of the module 22 for managing the payment means firstly converts accumulated points into an available sum of money called a virtual sum. Secondly, the calculation means of the module 22 of managing the payment means add this virtual available sum of money to the so-called real available sum of money corresponding to a real sum of money paid using the payment means of the game machine 2. The result of this addition, corresponding to the available sum of money displayed, is transmitted to the dialog module 10 of the juke box which then sends information permitting the display on the game machine 2 of the welcome screen comprising the display of the calculated available sum of money.

The welcome screen may also include a virtual button which when it is selected, triggers a payment procedure managed by the module 22 of managing payments and the graphic management module 21. This payment procedure firstly comprises the sending, by the dialog module 10 and then the display of a payment screen by the module 21 of graphically managing the display means 210 of the electronic game machine 2. This payment screen includes a text area describing at least one rule of payment. By rule of payment one should understand a rule which defines the sum of money necessary to purchase a determined whole number of credits of musical selections. The module 22 for managing the means of payment checks the value of the sum available (possibly containing a real sum and a virtual sum as previously defined) and sends a notification to the dialog module 10 of the juke box containing the total sum of money available for the identified game machine 2. On the reception of this notification, the juke box determines that they are the rules of payment authorized from among the list of available rules of payment and then sends the information that permits the display on the game machine 2 of the payment screen indicating, by a specific display, which are the authorized rules of payment in relation to the available sum of money. If no authorized and displayed rule of payment on the screen satisfies the user, that is to say if the amount available is insufficient to purchase the desired number of credits for musical selections, the user can then insert a sum of money or a means of payment in the game machine 2 in order to increase the amount available.

For each amount of money detected by the means of payment 220 of the game machine 2, the third management module 22 of the means of payment notifies the dialog module 10 via the notification means of the amount inserted into the electronic game machine 2 and modifies the value of the amount available. Upon receipt of the information corresponding to the amount received by the electronic game machine 2, the jukebox 2 determines the new value of the amount available and sends a message interpreted by the graphic module 21 in order to display a new payment screen in which new authorized rules of payment can be displayed, if the sum of money inserted permits.

The payment screen can include a virtual validation button, the selection of which causes either validation of the selected payment rule by the user from among the authorized payment rules and return to the welcome screen, or simply return to the welcome screen if no payment rule has been selected by the user. When a payment rule is validated, the calculation means of the module 22 for managing payment means calculates the new value of the amount available by deducting from the total available sum, the sum of money corresponding to the rule of payment selected by the user in order to acquire a certain number of credits. When the total available amount includes a virtual part and a real part, the calculation means use predetermined rules that define the proportions in which the virtual and real parts must be used in order to deduct the sum of money from the available amount. Hence, it may be previously defined by parameters that the virtual part is used up as a priority or that the virtual and real parts of the total available amount are used in an identical way.

The new available amount and the chosen payment rule are notified to the dialog module 10. On reception of this notification, the dialog module 10 sends a message interpreted by the graphic module 21 in order to display the welcome screen, possibly with the new available amount and the new number of credits for musical selections. The number of credits available is stored and updated, either on the game machine 2 or on the juke box. In the latter case, the value of the number of credits is associated with the identification of the corresponding game machine 2. In the case where the value of the number of credits is stored on the game machine 2, updating of the value of the number of credits available is carried out by sending a message from the dialog module 10 to the module 22 for managing payment of the game machine 2 indicating the new value of the number of credits. On reception of this message, the module 22 for managing payment carries out the update locally on the game machine 2.

In the case where the value of the number of credits is stored on the juke box, the value of the number of credits is increased locally on the juke box, on reception of notification indicating the payment rule selected after validation by the user.

In an embodiment variation, the modification of the amount available can occur at any time through the insertion of a sum of money or of a means of payment into the game machine. In this variant, for each sum of money detected by the means 220 of payment of the game machine 2, the third module 22 for managing the payment means notifies the dialog module 10 by means of notification means, the amount inserted into the electronic game machine 2 and modifies the value of the amount available. On receipt of information corresponding to the amount received by the electronic game machine 2, the juke box 1 determines the new value of the amount available and sends a message interpreted by the graphic module 21 in order to modify the current screen in such a way that the displayed amount available corresponds to the calculated amount.

In an embodiment variant, it is possible that the minimum payment amount for the game machine 2 is greater than the minimum payment amount for the rules of payment of the juke box. By way of example, the minimum amount for the payment for a single selection is 1 franc while the minimum amount for the payment of one party on the game machine is 5 francs. Hence the case can occur that after selection of a payment rule, the remaining amount available is 3 francs and after using musical selection credits, the user swings over to the first operating mode corresponding to the original operating mode of the game machine 2. In this case, the module 22 managing the means of payment transfers an amount available which is not, a priori provided for permitting use of the game machine 2 in games mode. To remedy this situation, the means, for example the software, permitting operation according to the first mode are modified so that they take all the amounts into consideration. Another solution consists of displaying on the payment screen only the rules of payment, for which the amount corresponds to a multiple of the minimum amount accepted by the game machine 2 in games mode. Finally, another solution consists of displaying on the payment screen only the rules of payment, selection of which ends up with either a reduction of the amount available to zero or reduction of the amount available to a value at least equal to the minimum payment amount for the game machine 2.

Selection of a musical work by the user is carried out by interactions with the welcome screen. As previously explained, the interactions of the user with the selection means 211 of the game machine 2 are translated by the graphic management module 21 into messages which are then transmitted by means of notification means 23 to the dialog module 10 of the juke box 1 to trigger the corresponding action, that is to say to send information permitting the display of a new screen on the machine or the modification of a screen.

When the user validates or confirms a musical selection made via a given action at the interactive means 211 of the electronic game machine 2, for example on a virtual validation button, the graphic management module 21 sends a notification to the dialog module 10 containing validation information and an identification of the selection. Upon receipt of this notification, the dialog module 10 then verifies the number of credits available. If the number of credits is different to zero, the dialog module 10 causes the activation of a jukebox 1 software module allowing insertion of the chosen selected work into a queue, with a view to play back thereof on the sound and video playback means of the jukebox 1, then deducts from the available credit balance an amount corresponding to the ordered selection. Finally the dialog module 10 sends a message which is interpreted by the graphic module 21 to allow the display of the welcome screen possibly with the amount of money available and the new number of credits for musical selections.

If the number of credits is equal to zero, the dialog module 10 sends a message interpreted by the graphic module 21 to display the payment screen previously described in such a way that validation of the selection is only confirmed if the user selects and validates a payment rule as described previously.

At any time, starting from the welcome screen, the user can actuate the activation means so as to switch the operating mode of the game machine 2 to the first operating mode corresponding to the original mode of the machine 2.

If the user selects the first operating mode by activating the activation means, the management module 21 initiates the notification means to send a notification of end of connection to the dialog module 10. Upon receipt of this notification, the dialog module 10 of the jukebox issues a termination message to the supervisor module 20 of the machine and switches the connection off. Upon receipt of this message, the supervisor 20 activates the second routine causing the cancellation of the tasks run by the graphic management module 21 and by the payment module 22 so as to activate again the original functions and tasks of the game machine 2. In the course of this shut down process, the module 22 for managing payment means transfers the total amount available, if it is different to zero, to a specific module for managing payments of the first operating mode. If the total available amount includes a residual virtual amount and a real amount, the calculation means of the module 22 for managing payment means, carries out the reverse conversion of the residual virtual amount into points and transfers the result of this conversion to a specific software module providing for operation of the game machine 2 according to the first mode. Similarly, the value of the number of credits usable for musical selections is stored, either in storage means of the game machine 2 by the module 22 for managing payment means, or in storage means of the juke box. In this latter case, the module 22 for managing payment means notifies, using notification means, the dialog module 10 of the juke box by indicating in a message, the value of the number of remaining credits and an identification of the game machine 2 issuing the notification. On receipt of this notification, the dialog module 10 stores the sent number of credits and links to it the identifier of the game machine 2 that issued it.

Finally, the selections made by the user and introduced into the queue with a view to playback thereof will be played back as if they had been chosen by using the user interface of the jukebox.

In an alternative embodiment, each electronic game machine 2 comprises an identification means in relation to the dialog module 10, so that, when the jukebox is connected to several game machines 2, it can asynchronously manage the communication with the various game machines 2. If a single game machine is connected to the jukebox, the identification of the game machine 2 enables the operating system of the jukebox to simultaneously manage the selection operations at the game machine 2 and those performed at its own interactive means.

The contents of the screens displayed on the viewing means of each game machine 2 are dependent not only on the processing capacity of the viewing means of the game machine 2, but also on the maximum rate of data transfers authorized on the LAN. The higher the transfer rate, the better the display quality and quantity will be.

In another alternative embodiment, each electronic game machine 2 can comprise a statistics report module (not shown). This statistics report module includes collecting means for collecting information on the utilization of the game machine 2 when it is operating according to the first mode, i.e. according to its original operating mode. The information regarding the utilization of the game machine 2 is stored in the storage means of the machine 2, e.g. in a log file. The statistics report module includes a link with the notification means, so that the file or the statistical information contained in this log file is transmitted to the jukebox dialog module 10. The transmission of this information is initiated by the statistics report module, either at each connection of the game machine 2 on the LAN 3, or at regular intervals, or when the quantity of information to be transmitted reaches a determined threshold. When the dialog module 10 of the jukebox receives this information, it stores it in turn in its storage means in a log file. When the jukebox 1 logs on to a remote server 5, in order to update selection information or to send jukebox utilization data, the information regarding one or more game machines, contained in the jukebox log file can be transmitted on demand to the server to be used, e.g. for business purposes.

The utilization information of the game machine 2 is for instance the quantity of the amount of money entered into the game machine 2 when it is operating according to the first mode or, if the game machine 2 includes several games, the game most often chosen, or else other statistical information etc.

Also, the game machine 2 can contain an update management module enabling a remote server 5 to be used for updating the operating system of the game machine 2. For this purpose, the update information is first downloaded into the jukebox by announcing the identifier of the game machine 2 for which the update is meant. Then, the jukebox dialog module 10 can set up a connection with the update target game machine 2 in order to send the required information thereto. In another alternative embodiment, sending the update information is performed as soon as the game machine 2 notifies the dialog module 10 that it is connected.

We are now going to describe the communication method according to the invention with reference to FIG. 2.

The first step 301 of the method according to the invention consists of operating the activation means to switch operation of the game machine into the second mode. This activation initiates, in a second step 302, a set up of the connection between a game machine 2 and jukebox 1. This setting up consists of activating the jukebox dialog module 10 and the graphic management 21 and payment 22 modules of the game machine. Next, in a third step 303, a display made on the viewing means prompts a choice of a musical selection. The display step also comprises a step of collecting and/or calculating the amount of money available and possibly the remaining number of credits.

Several actions are possible on the part of the user. Consequently, the machine is standing by for a user interaction.

Hence, in a first case, the machine is waiting, in a fourth step 304, for the user to validate a payment procedure by acting on the interactive means of the game machine 2. If such is the case, a payment screen is displayed in a fifth step 305. As previously explained, this payment screen comprises the list of available payment rules. Next the machine waits, in a sixth step 306, for the user to insert a means of payment (coin, ticket, credit card etc.) The insertion of a means of payment causes, in a seventh step 307, a notification to be sent to the jukebox containing information representative of the detected amount. The jukebox responds to this notification by sending the game machine a message that permits modification of the payment screen in order to display, in accordance with the fifth step, the new amount available and possibly the new rules of payment available. As soon as the user inserts a means of payment, the seventh step and a return to the display 305 of the payment screen is carried out. In an eighth step 308, the machine 2 waits for the user to select a payment rule and/or a means of validation such as a virtual button on the payment screen in order to return to the welcome screen. If a payment rule is selected before the selection of the means of validation, in a ninth step 309 the graphic management module 21 sends, to the dialog module 10, a notification representative of the payment rule selected by the user. In this ninth step 309, and on receipt of this notification, the dialog module 10 increases the number of credits and reduces the amount available and then sends a message to the graphic module in order to display, in accordance with the third step 303, the welcome screen with the new credit values and the amount available. If no payment rule is selected, before the selection of the means of validation, the graphic management module 21 notifies it to the dialog module 10, by indicating to it that no payment rule has been selected. On receipt of this notification, the module again carries out the third step 303 of displaying the welcome screen.

If triggering of the payment procedure, as previously defined, is not carried out, while the welcome screen is displayed, in a tenth step 310, the machine waits for insertion of a means of payment. If a sum of money is inserted into the machine 2, in an eleventh step 311, a notification generated by the module 22 managing the payment means and containing information representative of the amount detected, is sent to the dialog module 10 of the juke box. The dialog module 10 of the juke box responds, in the eleventh step 311, to this notification by sending to the game machine, a message permitting modification of the welcome screen to display, in accordance with the third step 303, the new amount available.

If no sum of money is detected, during display of the welcome screen in the third step 303, the machine awaits, in a twelfth step 312, activation of the activation means in order to switch the operation of the game machine from the second mode (juke box interface mode) to the first mode (original mode of the game machine). If this activation is detected, a thirteenth step 313 is triggered in which the tasks specific to the choice and to the payment for the selections on the game machine are closed by the dialog module and the connection between the juke box and the game machine 2 is broken. The thirteenth step also comprises the transfer, by the module 22 for managing the payment means, to the specific means of the game machine, of the remaining amount available and unused at the time of switching over to first mode.

During display of the third step 303, the user may, in a fourteenth step 314 use the interactive means to choose a musical selection. When the selection made has been validated by the user, the graphic management module 21 notifies the dialog module 10 of information representing the identification of the selection made. Upon receipt of this notification, in a fifteenth step 315, the dialog module 10 checks whether the credit balance is equal to zero.

If the credit balance is zero, the method according to the invention triggers the payment procedure through a fifth step 305. The procedure is identical, except for the fact that after the eighth step 308 of the payment procedure, the dialog module 10 is notified by the module 22 for managing payment means in order, in a sixteenth step 316, to insert the selection made and validated, into a queue of selections to be played back, and in order to deduct a credit from the total number of credits. Next, the dialog module 10 sends a message causing a return to the third step 303 of displaying the welcome screen with an update of the number of credits.

If, in the fifteenth step 315, the credit balance is different from zero, the dialog module 10, in the sixteenth step 316, inserts the chosen and validated selection into a queue of selections to be played back and deducts a credit from the total number of credits. Next, the dialog module 10 sends a message causing a return to the third step 303 of displaying the welcome screen with an update of the number of credits.

Thus, the communication device according to the invention is characterized in that each electronic game machine 2 is connected to the playback system 1 via a network interface 23 and an associated LAN 3 and comprises specific means 22 for managing the means of payment, specific means 21 for managing the viewing means, and the interactive means, in order to enable, on the electronic game machine 2, the selection of payment for at least one selection stored on the playback system 1 with a view to playback thereof on the playback system, the specific means 22 of managing the payment means and the specific means 21 of managing the viewing means and the interactive means being triggered by the activation means of the electronic game machine 2.

In another embodiment, the playback system 2 comprises a means 11 communicating with the communication interface 23 of each electronic game machine 2, a specific module 10 for managing messages coming from each electronic game machine 2.

In another embodiment, each electronic game machine 2 comprises identification means enabling differentiation at the playback system 1.

In another embodiment, the playback system 1 comprises means 13 communicating with a remote centralized server 5.

In another embodiment, each electronic game machine 2 comprises a means allowing to store information regarding the utilization of the electronic game machine.

In another embodiment, the specific means 22 of managing the payment-means comprise means of calculating the amount available to pay for the songs, firstly from a sum of money inserted by the user into the electronic game machine 2, secondly from a remaining amount of money inserted into the game machine 2 before triggering of the specific means 20, 21, 22 of management and thirdly from a number of game points accumulated before triggering of the specific management means 20, 21, 22.
